      and after several errors like that the server died.

      I am attaching an objdump as suggested at the server.log and the log itself with the errors and the crash.

      Thanks to the limitation uploading files here, I cannot update the whole log, just the object dump in two parts – used split to break in two pieces, then I could upload them.
